Smooth stone is the clean, borderless gray block builders love, and it is also the block you need to craft a blast furnace and an armor stand. The trick that catches people out is that you do not smelt cobblestone to get it. You smelt stone, which means smelting twice.
This guide covers the two-step smelting process, how to make smooth stone slabs, the furnace gotcha, and everything smooth stone is used for. Everything here is accurate for the latest 2026 version of Minecraft.
Quick answer: smelt regular stone in a furnace to get smooth stone. Since mining gives you cobblestone, smelt the cobblestone into stone first, then smelt that stone again into smooth stone.

How to Make Smooth Stone
Smooth stone takes two trips through a furnace because mining stone drops cobblestone, not stone:
- Smelt cobblestone into stone. Put cobblestone in a furnace with fuel and it becomes regular stone.
- Smelt the stone into smooth stone. Put that stone back in the furnace and smelt it again to get smooth stone.
That second smelt is the step most people miss. If you only smelt once, you just have plain stone, not the smooth version.
Furnace Only: Not a Blast Furnace
Just like green dye, smooth stone can only be made in a regular furnace. A blast furnace is for ores and metal, so it will not smelt stone into smooth stone. Use a plain furnace for both smelting steps.
Smooth Stone Slabs
Slabs are one of the most popular reasons to make smooth stone, because the smooth stone slab has a clean, distinct look:
- Crafting table: place 3 smooth stone in a row to get 6 smooth stone slabs.
- Stonecutter: put in 1 smooth stone to get 2 slabs, which is the more efficient method.
Smooth stone slabs also generate naturally in villages, strongholds, woodland mansions, and trail ruins, so you will often find them while exploring.
What Smooth Stone Is Used For
Beyond building, smooth stone is a key crafting ingredient:
- Blast furnace: 3 smooth stone + 1 furnace + 5 iron ingots. A blast furnace smelts ores and metal twice as fast, and it is also the job block for an armorer villager. See our best Y level for iron guide to gather the iron fast.
- Armor stand: 6 sticks + 1 smooth stone slab to display your gear.
- Building. Its clean, seamless texture makes smooth stone and its slabs a favorite for modern and industrial builds.
Frequently Asked Questions
Smelt regular stone in a furnace. Because mining drops cobblestone, you smelt cobblestone into stone first, then smelt the stone again into smooth stone.
Stone comes from smelting cobblestone once and has a slightly textured look. Smooth stone comes from smelting that stone a second time and is a clean, borderless gray.
No. Smooth stone must be made in a regular furnace. A blast furnace only smelts ores and metal.
Put 3 smooth stone in a row on a crafting table for 6 slabs, or use a stonecutter for 2 slabs per smooth stone.
Crafting a blast furnace and an armor stand, making smooth stone slabs, and building with its clean texture.
You are probably only smelting once. Cobblestone smelts into stone, and you have to smelt that stone a second time to get smooth stone.
Smooth stone is one of the most useful blocks in the game once you know the double-smelt trick. Stock up on it for slabs, a faster blast furnace, and clean builds. For the iron your blast furnace needs, check our best Y level for iron guide.
